Although there are strict limits for the amount of arsenic level allowed in water, there are currently no maximum levels in food - and now some scientists are speaking out as they are concerned about the effects of long-term exposure. In November 2012, Consumer Reports magazine published "Arsenic in Your Food," a report on arsenic in rice and foods made from rice.
